This is on the site, "Note that the repair site information provided by Zeus Mining free of charge is based on the photos of the repair site, more detailed information needs to be verified by yourself, Zeus Mining does not assume other responsibilities."
It's good that you have picked this one, as I said before I personally trust zeusbtc and can vouch for them, I have had many successful deals with their founder even long before I knew he was the owner of zeusbtc, a very genuine and trustworthy person, but if zeusbtc tell you they don't guarantee the folks listed on that list, then you should be careful, I know they don't randomly list everyone but I highly doubt that the due diligence is good enough.
nly Alpha Asic Repair has a website.. The pictures zeus is talking about on their site tell me nothing and how could you verify them as legit. I have spoken with Alpha before and they seemed a little over anxious to get my machines
I know that "Alpha Miner" which is owned by Mike and their website is
www.alphaminer.io is legit, not sure if this "Alpha repair" is owned by the same company or not, I will hopefully have the answer by tomorrow and will let you know.
Edit: Mike replied, they are not related to the "Alpha repair" at all, using a similar name to a company that already exists makes me doubt them, I would be extra careful.
